基于百度指数的黑龙江省城市网络研究

Research of City Network in Heilongjiang Province Based on Baidu Index

通过网络获取2014,2015年黑龙江省城市间的年平均百度指数,模拟城市间信息流,利用Taylor的世界城市网络研究方法、C-Value和D-Value层次分析法,从城市信息流量、城市网络结构和城市在网络中的主导性与控制力3方面对黑龙江省城市网络进行研究。结果表明:(1)黑龙江省各城市信息流量的层级分布特征明显,全省城市信息流总量有较大增长,但不同城市的增长率差异显著,总体呈现不均衡发展态势。(2)黑龙江省城市网络结构极化,南部城市的信息流密度大于北部城市,佳木斯失去了副中心城市的地位,哈尔滨的核心地位强化。(3)哈尔滨在城市网络的主导性和控制力强度远大于其他城市,绥化、鸡西、双鸭山和佳木斯的主导性和控制力强度增长明显,城市的主导性和控制力强度与其信息流量大小没有必然关系。

In this thesis,the author gets the intercity average annual baidu index of Heilongjiang Province in 2014 and 2015 from the Internet to simulate the information flow among the cities. Then the author borrows ideas from Peter Taylor's world city network research methods and hierarchical methods of C-Value and D-Value and analyzes the network among the cities in Heilongjiang Province in terms of the total amount of information flow,urban structure of the network,the city's dominance and control in the network. The study shows that:( 1) There exists obvious hierarchy in the total amount of information flow in different cities. The total amount of urban information flow has increased significantly,but the growth rate of the cities is quite different with imbalance of development as a whole.( 2) The urban network of Heilongjiang Province displays polarization with the information flow distribution density greater in the south than in the north. Jiamusi has lost the status of sub-center city,while Harbin's dominance has strengthened.( 3) The dominance and control of Harbin in the city network has much higher than other cities. The dominance and control in cities like Suihua,Jixi,Shuangyashan and Jiamusi has strengthened significantly. The amount of information flow is independent of a city's dominance and control.
